Police first spotted Ms. Asanovska’s boyfriend, Isa Martin, 27, of the 1,000 block of Castleton Avenue, with an open bottle of Hennessy cognac at the corner of North Burgher Avenue and Wayne Street, authorities allege.

When police determined they had a warrant for his arrest — it’s not clear what for — he ran off and hopped into Ms. Asanovska’s car, authorities said.

She then blasted through two steady lights on Henderson Avenue and sped over a speed bump before pulling over, authorities allege.

Martin ran out, but was captured and charged by police with third-degree criminal weapon possession after, authorities allege, officers found a switchblade in his pocket, as well as obstructing government administration and resisting arrest.

After she pulled over, Ms. Asanovska left the car and, with the baby in her arms, shouted and swung her arm at a police officer, authorities said.

She’s charged with resisting arrest, obstructing government administration, second-degree reckless endangerment, endangering the welfare of a child and reckless driving.
